how do i write the intercept form equation
y=a(x-p)(x-q)
when i know a=-16
p=-0.12
q=1.12

Answers

Answer:

y = -15x - 3.04

Step-by-step explanation:

1) First place down what you are given.

Y = a(x - p) (x - q)

2) Then Substitute.

a = -16

p = -0.12

q = 1.12

y = (-16)(x - (-0.12))(x - (1.12)

3) Do order of operations (PEMDAS)

y = (-16)(x + 0.12)(x - 1.12)

Now distribute

y = − 16 x  −  1.92 + (x - 1.12)

y = -16x - 1.92 + x - 1.12

y = -16x + x - 1.92 - 1.12

y = -15x - 3.04

4)

You answer is:

y = -15x - 3.04

Step-by-step explanation:

x= 4

y= 16

h= 5

10(4) + 5.5(16) + 15(5)

40 + 88 + 75

203

Answer:

$93.50

Step-by-step explanation:

Ok so divide $10.00 by 2 which is $5.00 and divide $5.50 by 2 which is $2.25 and divide $15 by 2 which is 7.50. Since there was 4 adults so it cost $20.00 because 5.00X4=20.00. Since there was 16 kids going it cost $36.00 because $2.25X16=36. Since they were there for 5 hours it cost $37.50 because $7.50x5=$37.50. Add all of those up and you will get $93.50.

The greenhouse club is purchasing seed for the lawn in the school courtyard. The club needs to determine how much to buy. Unfortunately, the club meets after school, and students are unable to find a custodian to unlock the door. Anthony suggests they just use his school map to calculate the area that will need to be covered in seed. He measures the rectangular area on the map and finds the length to be 10 inches and the width to be 6 inches. The map notes the scale of 1 inch representing 7 feet in the actual courtyard. What is the actual area in square feet?

Answers

Answer:

The answer is 2940ft^2

Step-by-step explanation

First convert length and width to feet using the value given (7ft=1inch).

[tex]10*7= 70[/tex]

[tex]6*7= 42[/tex]

Multiply these values for the actual area.

[tex]42*70= 2940[/tex]

The actual area of the lawn is 2940ft^2

An aircraft factory manufactures airplane engines. The unit cost C (the cost in dollars to make each airplane engine) depends on the number of engines made. If x engines are made, then the unit cost is given by the function C(x)=0.5x^2-330x+65,738. How many engines must be made to minimize the unit cost? Do not round your answer

Answers

Answer:

330 engines

Step-by-step explanation:

If the unit cost is given by the function C(x)=0.5x^2-330x+65,738 where x is the amount of engines made while C(x) is the unit cost. In order to know the amount of engine needed to minimize the cost;

we will first find dC/dx and equate the resulting function to zero to get x.

dC/dx = 2(0.5)x - 330

dC/dx = x - 330

since dC/dx = 0

x - 330 = 0

x = 330 (critical point)

Then find the second derivative to check if it is greater than zero.

d²C/dx² = 1

Since d²C/dx² > 0, then the cost will be at the minimum when x = 330

Substitute x = 330 into the modeled function;

C(330)=0.5(330)^2-330(330)+65,738.

C(330)= 54,450-108,900+65,738.

C(330)= -54,450+65,738.

C(330)= 11,288

Hence the amount of engines that must be made to minimize the unit cost is 330 engines and the unit cost at the minimum price is 11,288

The boiling point of water is 212∘F. In degrees Celsius, how much heat do I have to add to boil water that is already 194∘F? Use the formula C = 59(F − 32), where C represents the temperature in degrees Celsius and F represents the temperature in degrees Fahrenheit.

Answers

The amount of heat to add to boil the water is 42000J

What is specific heat capacity?

The specific heat capacity of a substance is the energy required to raise the temperature of of the substance by 1°C or 1k. It is measured in J/kg/k

The amount of heat to raise temperature is given as

H= mck

where k is the temperature change.

converting 212°f to Celsius

C = 5/9( 212 -32) = 5/9 × 180

= 100°C

converting 194°f to Celsius

C = 5/9( 194 -32)

C = 5/9 × 162

C = 90°C

Therefore;

H = 4200 × 100-90

H = 42000J

Therefore, the amount of heat to boil the water is 42000J.

Find the equation of a line when y-intercept is 2, and gradient is -2/3

Answers

Answer:
y=-2/3x+2

Explanation:
When we need to find the equation of a line and the question gives us the slope/gradient and y-intercept, we organize our answer in slope-intercept form.

Slope intercept form: y=mx+b

Here’s what the variables mean:
Y=the y coordinate
M=the slope/gradient
X=the x coordinate
B=the y-intercept (the point on the line that intercepts the y-axis)

Now, all we have to do is plug in the given information. The m variable is the slope of the line so we plug in -2/3 as m.

y=mx+b
y=-2/3x+b

And the b variable is the y intercept so we plug in 2 as b.

y=-2/3x+2

There are 3,785 milliliters in 1 gallon, and there are 4 quarts in 1 gallon. For each question, explain or show reasoning.

1. How many milliliters are in 3 gallons?

2. How many milliliters are in 1 quart?

(Note) Please keep reasonings simple

Answers

Answer:

There are 11,355 milliliters in 3 gallons, and 946.25 milliliters in 1 quart.

Step-by-step explanation:

If there are 3,785 milliliters in 1 gallon, multiply each side by 3 because you want the product to equal 3 gallons.3,785 times 3 is equal to 11,355, and 1 times 3 is 3. So, 3 gallons are equal to 11,355 milliliters. If there are 3,785 milliliters in 1 gallon, and there are 4 quarts in 1 gallon, that means that there are 3,785 milliliters in 4 quarts. Now, you want to find the amount of milliliters in 1 quart so you should divide both the 3,785 and the 4 by 4. So, there are 946.25 milliliters in 1 quart.

Answers

Answer:

1. 2(x - 5) = 2(x - 5) has infinitely many solutions

2. 5(x + 4) = 5(x-6) has no solution

3. 5(x + 4) = 3(x-6) has one solution

4. 4(x - 2) = 4(x + 2) has no solution

5. x + 2(x - 5) = 3(x - 2) - 4 has infinitely many solutions

Step-by-step explanation:

I did the assignment and I got it correct edge2020

1. 2(x-5)= 2(x-5) = Infinitely many solutions.

2. 5(x+4) = 5(x-6) =  No solution

3. 5(x+4) = 3(x-6) =  One solution

4. 4(x-2) = 4(x+2) = No solution

5. x+2(x-5) = 3(x-2) - 4 = Infinitely many solution

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Now,

The given equations is;

1. 2(x-5) = 2(x-5)

2x-10 = 2x-10

0=0

Hence, This equation has infinitely many solution

2. 5(x+4) = 5(x-6)

5x+20 = 5x-30

20 ≠ (-30)

Thus, This equation has no solution

3. 5(x+4) = 3(x-6)

5x+20 = 3x -18

5x-3x = -20-18

2x = -38

x=-19

Thus ,this equation has one solution

4. 4(x-2) = 4(x+2)

4x-8 = 4x+8

-8 = 8

Thus, this equation has no solution

5- x+2(x-5) = 3(x-2) -4

x+2x-10 = 3x-6-4

3x-10 = 3x-10

0=0

Thus, this equation has infinitely many solution
